TypeError: Unicode-objects must be encoded before hashing What is wrong?

I got an error,TypeError: Unicode-objects must be encoded before hashing. I wrote codes,

        user = Data()
        passwd = request.data['password']

        md5 = hashlib.md5()
        md5.update(passwd)

        user.password = md5.hexdigest()
        print(user.password)

        user.save()

Traceback　says

    md5.update(passwd)

I added #coding:utf-8 to top of the code,but same error happens.What is wrong in my codes?How should I fix this?

The error tells you what you need to do: encode the password to a bytestring.

md5.update(passwd.encode('utf-8'))

Note though you probably shouldn't be doing this at all; if you want to use a user's password, use the set_password() method of the User model.

(And please don't randomly add encoding declarations to your script; that only effects literal characters in the file.)
